Operating Theory

1. Sequence SK,2SK Drinking water Ring Vacuum Pumps can be employed to exhaust normal gases as well as condensable gases(these kinds of as drinking water vapor). Simply because they have the features of isothermal compression, they can exhaust flammable and explosive gases. When the pump created up of anti-corrosion content is selected, it can be employed for exhausting corrosive gases way too. 


   2SK collection two-phase liquid ring vacuum pumps can operate properly like two sets of SK collection h2o ring vacuum pump. Because of to SK series vacuum pumps only get to the maximum vacuum of-700mmHg, to satisfy the high vacuum and the massive pumping velocity underneath high vacuum, China created the 2SK collection h2o ring vacuum pump in 80s in the 20th century. 


two. Collection 2YK Liquid Ring Vacuum Pumps have the attributes of larger vacuum and better applicability. The distinct types of gases can be pumped with the chosen appropriate working media. Consequently, they can be used in broader variety.


3. The pumps run efficiently with lower noise and usage. The power-saving is 30 per cent comparing with the Water Jet and the Drinking water VaporJet Pumps.





one. In comparison with SK water vacuum pump ,It receives higher vacuum and pumping velocity and so on..

two. Straightforward construction and effortless routine maintenance.

3. The largely functioning medium is h2o and lower servicing fees.

four.The pump is widely use in a lot of areas and suction drinking water vapor,flammable, explosive and different gases have a little amount of dust and liquid.

five. The pump can performs in the harsh condition

1. In comparison with SK h2o vacuum pump ,It will get substantial vacuum and pumping speed and many others..

two. Straightforward construction and easy upkeep.

three. The largely doing work medium is h2o and reduced maintenance charges.

four.The pump is commonly use in many locations and suction water vapor,flammable, explosive and numerous gases incorporate a tiny volume of dust and liquid.

5. The pump can functions in the severe condition

Regular Selection for Water(Liquid)Ring Vacuum Pump

one,Based on the vacuum value
(one)If the pump is operated for long time with the inlet pressure range between1.3×104~1×105Pa (between 100 and 760 Torr), please choose series SK Water Ring Vacuum Pump.
(2)If the pump is operated for long time with the inlet pressure range between5×103~one.3×104Pa(between40 and 100 Torr), please choose series 2SK Water Ring Vacuum Pump.
(3)If the pump is operated for long time with the inlet pressure range between1×103~1.3×104Pa(between8 and 100 Torr), please choose series 2YK Liquid Ring Vacuum Pump.

two,Working Media 
There are four principles to choose working media(i.e.ring liquids)
(one) Lower saturated steam pressure
(two) Lower viscosity
(three) Stable physical & chemical features no chemical reaction with the pumped gasno corrosion to the pump no pollution to the environment.
(four) Economy

      If the drinking water is selected as the operating medium, the very best temperature of offer drinking water must be lower than or equivalent to fifteen °C the highest 1 must not be larger than 40°C. Although the transformer oil or other lower viscosity and saturated vapor strain industrial oils are as the operating media, the common source temperature need to not larger than 40°C and the functioning media temperature inside the pump chamber ought to not be larger than 60C, when the liquid with lower boiling level is picked as the working media below some special circumstances, the cooling device need to be geared up to amazing down the operating media in get to guarantee that the max temperature is 30ºC-50ºC, reduced than the boiling point. For the closed circulated program of working media, the liquid storage unit and cooler should be geared up, and the gas-liquid separator have to be set up at outlet. The mechanical seal need to be employed for dynamic seal of the shaft.

3,Choose the dynamic seal of the shaft:
Choose the packing seal in general occasion choose the mechanical seal when the pump is used in no leak occasion.

4,Choose the material of the part that the gas passed:

(1) For the non anti-corrosion pump, the shaft is produced of forty five#metal or 40Cr, other elements are created of forged Iron or brass

(2) For the anti-corrosion pump,the parts that the fuel handed, need to be produced of stainless metal 304 and 306, or other material appropriate for the respectively corrosive gasoline, or the areas must be set with anti-corrosion coating.

five, The motor should be selected based on pumping pressure.

If the pump is employed for vacuuming even though transferring fuel, the strain of pump outlet exceeds the CZPT ambiance pressure.

When the outlet force exceeds .15MPa, the particular double-phases liquid ring compressor ought to be picked and not the vacuum pump refitted. Tthe electrical power of the equipped motor should be enhanced naturally. And the special gas-liquid separator and vehicle-drain unit must be equipped also.

When the outlet force is underneath .15MPa, it can use the vacuum pump refitted as compressor. The power of the geared up motor must be enhanced effectively.

6,Composition methods of the water ring vacuum pump system
The opening circulation system should be used if the working liquid in the outlet need not be circulated or partially circulated.
The closed circulation system should be used if the working liquid in the outlet must be circulated.

Broadly utilised in papermaking, chemical, petrochemical, light-weight industry, pharmaceutical, food, building components, electrical appliances, coal washing and  mineral dressing industry, fertilizer, and so forth. 
In the coal sector, it can especially pump highly flammable and explosive gas, these kinds of as mash gasoline, methane, can design set up of floor fuel drainage station, can sort a complete established of cellular gas drainage method.
